[CH2:1]([O:3][C:4]([C:6]1[CH:10]=[C:9]([CH2:11][OH:12])[O:8][CH:7]=1)=[O:5])[CH3:2]>ClCCl.[O-2].[O-2].[Mn+4]>[CH2:1]([O:3][C:4]([C:6]1[CH:10]=[C:9]([CH:11]=[O:12])[O:8][CH:7]=1)=[O:5])[CH3:2]5-Hydroxymethyl-3-furancarboxylic acid ethyl ester (0.34 g, 2.0 mmol) was dissolved in dichloromethane (20 mL), manganese dioxide (1.4 g, 15.9 mmol) was added, and the mixture was stirred overnight. The reaction mixture was filtered through celite, and the solvent was evaporated under reduced pressure to give the title compound (0.26 g).
